sed search & replace

sharathkv25 · 03-07-2007, 07:17 AM

Hi,

I have a file 't.env' as follows:

Code:

ORACLE_BASE=/opt/oracle/
ORACLE_HOME=$ORACLE_BASE/bin/forms

How do I replace "$ORACLE_BASE/bin/forms" with my own string using sed?

In sed I used this:

sed -e 's/ORACLE_HOME/ORACLE_HOME=\/opt\/osmf\/config\/env/g' t.txt > t1.tx

But this replaces ORACLE_HOME & not the value after '='

Thanks

Code:

sed -ei 's#\$ORACLE_BASE/bin/forms#my/own/string#g' file.txt

-i for replacing directly in the file (maybe not what you want)
I have replaced the / of sed by #, you can use whatever delimiter you want. Then its more readable.

Code:

sed -e 's|$ORACLE_BASE/bin/forms|my/own/string|' t.env

Or:

Code:

sed -e 's|ORACLE_HOME=.*|ORACLE_HOME=my/own/string|' t.env
